question 13

Multiple Choice

The augmented matrix is given for a system of equations. If the system is consistent, find the general solution.
Otherwise state that there is no solution.
- $$\left[ \begin{array} { r r r r } 1 & 2 & - 3 & 5 \\0 & 1 & 4 & - 5 \\0 & 0 & 0 & 0\end{array} \right]$$

• A) \(x _ { 1 } = 5 - 2 x _ { 2 } + 3 x _ { 3 }\)
